  The results of the analysis of gravitational and magnetic fields of the Tersko-Caspian depression are introduced. The main feature of the potential fields of the region is the presence of high-gradient zones. Distributions of azimuths of gravity and magnetic lineaments testify to the coincidence of the basic maxima on histograms of directions of gradients. About the general nature of these zones caused fault tectonics.

A comparison shift the aggregate final volume and minimum sample value, depending on model parameters for parts excavator. The studies revealed the following pattern: in the range of the Range R = 17-20 sets of the coefficients are significantly different from the values ​​of other Ranges.

Keywords: General population of finite volume, scope aggregate, shift the aggregate, the minimum sample value, selection.

The method of definition distribution Fisher-Tippeta parametres of final volume population (Ас, Вс, Сс) under the selective data of the average stress is offered in the given work. Average values of parametres (Ас, Вс, Сс) thus is recommended to use at repeated modelling. Thus the Ас, Вс, Сс received is recommended to use average values of parametres at repeated modelling.

Keywords: the selective data, stress, Fisher-Tippet distribution, population, modeling.

  Current article presents the results of research, aimed at raising the effectiveness of automatic prosodic analysis of speech. During the research the PC program that performs recognition of seven emotional states using 16 features of speech signal was developed. Effectiveness of recognition of seven emotional states was estimated during the experiment with material of Berlin database of emotional speech. The result showed rising of mean probability of correct recognition, in comparison with known analogs.

  The article deals with the analysis of current legislative mechanisms of state policy implementation in the sphere of energy saving and energy efficiency. A number of crucial measures highlighted needed to ensure fulfillment of federal legislation requirements on energy efficient equipment and products while implementing state and municipal procurement procedures. The article notes problems occurring while implementing those requirements resulting from the absence of energy efficiency criteria and products life cycle cost while assessing and comparing applications. The article analyses the role and capacities of Moscow city which was selected as a pilot region to introduce energy efficiency labels and to ensure legislative and normative framework for order placement for municipal needs on the basis of energy efficiency standards and labels. The article points out that currently valid authority of the city touches on not only effective implementation of federal legislation but also issues related to the development of regional legislative framework.

  Methods of mathematical (geometric) modeling are often used in the current research of multivariate processes and their optimization tasks combined with traditional mathematical methods of experiment planning. This simulation is carried out by methods of descriptive geometry, its practical values a graphical representation of the functional relationships of the quality from factors and parameters that define a process with number of variables more than three. Definition’s algorithms of the optimization based on the Radishchev drawingin the article are given to ensure the visibility of images and solve certain technical problems. The graphical model of the process optimization of joining parts of garments was constructed.

Labour market is a complicated social and economic system, which requires the necessity to consider a number of characteristic properties (stochasticity,nonlinearity,inertance,nonstationarity) for investigation and modelling labor market processes and phenomena. In this article the problem of optimum control of a labour market is mathematically formalized. This allows for regional system of a labor market to reach desirable indicators, namely the set unemployment rate.
